Backfill easily only 1 minute data as in nest trader but ask bid data not not available in nest trader plus charts so not possible but if system is on from 9:15 to 3:30 and ninja running you can capture all ticks of asks and bids.I tested on yusi
large players uses these ask bid data to find exact resistance support levels.
It is verry difficult to maintain all month data with yusi utility,but we can help each other to give ask bid data offline if someone misses.
I dont know which data provider give level 2 data with timestamp backfill.
Without pain no gain.
